Timberwolves

Timberwolves are the most dangerous race of predators in the Everfree Forest. They spread out to many of Equestria's forests, but their biggest population is in the Everfree Forest. They are fueled by chaos magic from the Everfree, so the populations outside are smaller and not as strong. 

They are the biggest natural enemy of the grifix. Even when killed, they will often rebuild themselves out of wood. The grifix magic is the only kind of magic that can completely kill a timberwolf, but that is very hard and one grifix doesn't have enough power to do that.

Timberwolves can be scared by loud noise, but that doesn't always drive them away, especially when they are very angry.

They are the main cause of death for the Everfree Grifix after diseases and old age.
